Bits to Atoms: Co-op Quadcopter Challenge
This month’s Bits to Atoms project explores the idea of teamwork through quadcopter hacking. Jeremy and Sean set up a game for the Tested team to cooperatively pilot a quadcopter through an obstacle course, and Adam comes in to save the day with his decisive leadership.

That looks wildly fun, and a great team building exercise.
Thanks!
Those pigeons are going at it in the window. LOL
Great video as always!
This is great fun.
Few more days of training and you will be great at this new rising sport 🙂
That was great! Loving this series
Fantastic! Looks crazy fun!
Thus was UBER fun to watch… This should totaly become a partygame in a box!
That is such an awesome idea! I need to replace the broken motor on my Hubsan X4 and make one of these myself. Maybe even on my Syma X5C! I think my friends and I would have a blast with this.
I wonder how hard it would be for 1 player such that they need to use both hands and both feet. I think that would be super difficult. Maybe drummers would fare a little better!
By the way, as for your surprise that it worked with the extra wiring resistance, it’s not quite just a case of it being a sweep from zero(ish) resistance to full resistance – it’s a potential divider formed of two resistors, so think of a resistor from 3.3V to the wiper (sometimes called the tap), then another resistor from the wiper to ground, so as you turn the pot, one resistor increases and the other decreases. If drawn out schematically, with the top resistor (3.3V to wiper) being R1 and the bottom being R2, you’d get an output voltage of Vout = 3.3V * R2 / (R1 + R2).
By adding the long wires, you’re just increasing both resistors (although negligibly). The net result would be that you might have a total of just over 5k.
You could almost certainly use 10k pots instead of 5k and it would still function exactly the same as it’s purely ratiometric. 47k or 100k would probably even work, so that lends itself nicely to being able to use pretty much whatever you have laying around. They wouldn’t even need to all be the same.
If you could manage the actual soldering on the back of the board ,a big glob of hot glue (which is nonconductive) makes good strain relief.
Looked really fun. Disappointed that the controls were mostly knobs though. You might have been able to gear a lever so it wouldn’t need to match the throw of the potentiometer one to one. I was thinking you could use one of those sliding controls you see on sound boards to control up and down.
I love this series, keep up the great work guys!
My favourite Tested series! So much joy in this one!
That was great. Thanks for showing all of the fails too… That was the best part, watching the mind-meld between the 4 of them to become in sync. Loved it!
I think you guys need to take that to a toy company! 😀
Ha! Brilliant idea.
Please sir, can I some more of this.
That was amazing. I’ve always thought it would be really fun to hack a quadcopter to be controlled by a Raspberry Pi. Then you can program it to fly. I couldn’t figure out the control part though, but hacking the controller like you did looks easier than I thought. Great explanation on hacking the controller by the way. I loved watching Jeremy figure out how the controller worked by examining the PCB. Very educational. Great video guys!
Clearly, I was the weak link.
Star Trek Bridge Crew IRL…
That was ridiculously fun to watch !!!
So much so that I feel I must build one of these rigs for my family to try out.
Can you tell us what the quad copter you used was ?
Sean, love the MST3K shirt…Went and saw the live show with my son in Denver…It was great !!! If you get a chance to see it I highly recommend it…
Thanks !!!
Not true! To be fair, half the controls were wired backwards – we fixed it after you left…
I believe the Quad is this one, Jeremy can confirm:

It’s not Adam’s leadership, I’m pretty sure it’s just the hat.
This has reignited my interest in an exploded Guitar Hero controller for co-op single player games. One person per giant button!
You had me giggling right there. Great way to start my day. Thanks!
I was actually laughing out loud during the actual flying, this was super cool! 😀
This was amazing! I think you guys have stumbled upon something brilliant here. I’ll definitely be trying this out myself!
That was fun; it was crazy. That was crazy fun. You have made a four-person TARDIS.
Stumcconnel explained how a potentiometer works inside. To the rotary encoder point, rotary encoders are discs connected to the rotating shaft that are read optically. Picture a wheel with many black and white even divisions of 360 degrees or “spokes”. Microcontrollers read it by counting the changes from black to white or vice versa, but a dedicated part of the system must always be ready to “see” a change. That is done with hardware interrupts. That is a relative encoder, but absolute encoders also exist. Instead of solid spokes, those wheels can be read as binary numbers. Each “spoke” corresponds, in binary, to the position around the circle. Those are the best method for digitizing rotation, but they’re crazy expensive. Sometimes, instead of black and white printed spokes, manufacturers cut the disc into the same sort of patterns.
This was utterly ridiculous, and I loved every minute of it.
This was an amazing video. Wow!!!
This was amazingly fun to watch! Now, onto the drift and controlling a Jaeger!
Give it to Jeremy for is throttle control. Holding steady altitude is the hardest thing to master.
So awesome. I was thrilled when this showed up. You guys are two for two!
When Jeremy gets so excited he starts quoting Anikin in episode 1.
I do believe that’s the one. I actually have that one, and it looked the same.
This is so good guys. Top work!
Haven’t seen Jeremy having this much fun in a long time. Great to watch!
Loved the 4:3 montage 🙂
Best build ever!
This is the best Bits to Atoms project yet. I was giggling like a child when you were all trying to learn how to fly it. Keep ’em coming Jeremy & Sean!
Great vid, but I now have to find my Encom tshirt. : )
Bits to Atoms has risen quickly to be some of the best content on Tested. Well done everyone. Can’t wait to see more.
This is so excellent. Best type of team building exercise ever
